Officially support only Emacs 24.3 and later

[fice-t]

Closes #1218

Perhaps this should be merged after a new stable release has been created. Then in the readme there can be a link to the stable release saying "This is the last version that sort-of supports 24.1/24.2".

[gracjan]

Well, current master does not work with 24.2 so it would be a problem to claim it does.

[fice-t]

I suppose so. I was thinking that there should be a recent stable release that does support 24.1/24.2. Perhaps you could edit an older tag to include that info?

Actually, it turns out that haskell-mode v13.18 also has the error I mentioned here in 24.1.

Turns out that it's because locate-dominating-file doesn't accept a predicate as its 2nd argument before 24.3. This also means that 13.18 doesn't fully support 24.1, 24.2, or even 23.
13.16 seems to be fine.

[gracjan]

We can include this information in the manual. We have one paragraph about Emacs 23, we can have more.

[gracjan]

So, can you:

• add compatibility info in manual, there is a paragraph about this so next to it.
• change all instances of (defvar x ...) (make-variable-buffer-local 'x) into defvar-local
• change all instances of (set (make-local-variable ..) ..) into setq-local

?

This would clean up most glaring syntax problems.

[fice-t]

What should it say? That 13.16 is the last version to support <24.3 or 13.18? As it stands 13.18 doesn't.

[gracjan]

13.16

[fice-t]

Now the manual just points to 13.16 as the latest version for 23/24.1/24.2 support.

The setq-local/defvar-local stuff was done with a query-replace-regex, but it should be fine.

[fice-t]

@gracjan The release descriptions for 13.16 and 13.18 should probably get updated to match the manual.

[fice-t]

@gracjan Ah, also, are there any plans for the NEWS file? It hasn't been updated for a while.

[gracjan]

I don't have energy for that. If you want to fix it then there is 15 months of Haskell Mode reports as a source material.
